To achieve a flush fit between the hydronic front and the finished wall,
2
Dimension "C" must be between 3" and 3 1/8". If this dimension is
more than 3 1/8" there will be a gap between the front and the wall.
This gap could permit occupant access to hydronic lines or other danger-
ous parts.
3 This dimension can be from 0" to 3-1/4", but cannot exceed 3-1/4".
If this dimension exceeds 3-1/4", the skirt around the front will not
reach the floor.
• For installations in walls deeper than 13-1/2 inches,
special care is necessary to prevent problems with
rain water, condensate drainage and intake/discharge
air. Under these circumstances, careful job site analy-
sis and precautions are required. You must consult
with your Sales Representative and receive approval
before attempting such installations.
• If used, a 115 volt or 230/208 volt wall receptacle
must be located within 58 inches of the lower right
sleeve corner. Extension cords must not be used with
the unit. See the note on Wall Sleeve Dimensions Fig-
ure.

When 115 volt or 230/208 volt units are to be installed,
the power supply may be either cord connected or per-
manent wiring. Permanent wiring may be done through
C
the accessory hard wire junction box, or the accessory
mm
subbase.
0
When 265 volt units are to be installed, the power supply
70
must be permanent wiring. Permanent wiring may be done
50
through the accessory hard wire junction box, or the ac-
35
cessory subbase. An exposed cord connection on 265
0
volt units is not permitted.
0
The subbase accessory includes leveling legs. If added
752
wall sleeve support is required and the subbase is not to
65
be used as an accessory, leveling leg kit may be installed.
Drain Kit
An indoor/outdoor drain kit is available as an accessory
item. When a drain kit is to be installed, do so before in-
stalling the wall sleeve in the wall. See the drain kit for
actual installation instructions.
Subbase, Leveling Legs, Main Duct, and Hydronic Heat
Kits
Installation of these kits requires drilling of mounting holes
on both sides of the wall sleeve. The minimum required
clearance distance between the wall sleeve and wall is shown
in Minimum Clearances and Projections Table. If the dis-
tance between wall sleeve and wall will be at or near the
minimum clearance distance, mount these kits on the sleeve
before installing the sleeve in the wall. The kit installation
instructions are included with the accessory kits.
